DETAILED DESCRIPTION

[0028] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0029] The matching structure of a steel collar and a wire ring of a spinning machine in the present embodiment relates to the technical field of textile machinery. The direction of the center axis of the existing bearing 331 is changed so that the axis of the bearing 331 is perpendicular to the end face of the steel collar, thereby avoiding friction between the end face of the bearing 331 and the side of the steel collar. This can increase the service life of the steel collar-wire ring assembly and reduce problems such as yarn hairiness and yarn breakage during the spinning process.

[0030] See also Figures 1 to 4 In this embodiment, a matching structure of a steel ring and a steel wire ring of a spinning machine includes an annular base 100, a steel ring assembly 200 and a steel wire ring moving assembly 300. The annular base 100 can provide fixed support to connect the steel ring-steel wire ring with the lifting dragon bar.

[0031] The steel collar assembly 200 includes two symmetrically arranged steel collars 210, one end of which is provided with an annular groove 211, and the outer side of the steel collar 210 is detachably connected to the inner side of the annular base 100, and the steel collar 210 can be disassembled and assembled from the annular base 100 as needed, and the spacing between the steel collars 210 can be adjusted. The annular grooves 211 of the two steel collars 210 are arranged relative to each other to form a sliding space, and the sliding space can be used to install the wire ring moving assembly 300, thereby avoiding friction between the end surface of the bearing 331 and the steel collar 210.

[0032] The wire ring moving assembly 300 includes a wire ring body 310, a magnetic unit 320 and a bearing rolling unit 330. The bearing rolling unit 330 is arranged in the sliding space. The bearing rolling unit 330 includes two symmetrically arranged bearings 331. The axes of the bearings 331 are arranged perpendicular to the end faces of the steel collar 210. The outer rings of the two bearings 331 are respectively connected to the two side walls of the annular groove 211 in a rolling manner. The wire ring body 310 is respectively fixedly connected to the inner rings of the bearings 331. When the wire ring body 310 drives the bearings 331 to roll relatively, the bearings 331 and the side walls of the annular groove 211 roll relatively, generating rolling line friction, with low friction force, low friction resistance and low wear. The magnetic unit 320 is arranged between the bearing 331 and the bottom of the annular groove body 211. The magnetic unit 320 can use the magnetic field to keep the bearing rolling unit 330 suspended, avoid the bearing rolling unit 330 from contacting the bottom of the steel ring 210, and prevent the generation of sliding friction. It can improve the service life of the steel ring-wire ring assembly and reduce the problems of yarn hairiness and yarn breakage during the spinning process.

[0033] In some embodiments, see Figures 2 to 4The bearing 331 includes an outer ring 331a, balls 331b and an inner ring 331c. The outer ring 331a is sleeved on the inner ring 331c to form an annular gap. A plurality of balls 331b are arranged in the annular gap. The outer ring 331a is rollingly connected to the two side walls of the annular groove 211. The inner ring 331c is fixedly connected to the wire ring body 310. The outer ring 331a can rotate relatively to the inner ring 331c with low friction by means of the balls 331b, thereby reducing the friction and wear between the inner ring 331c and the outer ring 331a.

[0034] As a further embodiment, the bearing 331 further includes a retainer 331d and a sealing ring 331e. The retainer 331d is arranged in the annular gap, and a plurality of balls 331b are sequentially embedded in the retainer 331d. The retainer 331d can fix the balls 331b in a proper position, ensuring that each ball 331b is evenly distributed and maintains a stable spacing during the rolling process. This not only prevents direct collision between the balls 331b and reduces wear, but also ensures the smoothness and consistency of rolling, further reducing friction resistance.

[0035] Two sealing rings 331e are arranged at both ends of the bearing 331. The sealing rings 331e are specifically made of rubber or engineering plastics. The sealing rings 331e are tightly fastened to the inner ring 331c. The two sealing rings 331e close the annular gap. Lubricant can be injected into the annular gap in advance to further reduce the friction between the inner ring 331c and the outer ring 331a. The presence of the sealing ring 331e can effectively prevent the lubricant from leaking out, ensuring that the inside of the bearing 331 is always fully lubricated. The improvement in the lubrication effect reduces the heat and wear generated by rolling friction, and further extends the service life of the bearing 331 and related components. The sealing ring 331e can not only prevent the leakage of lubricant, but also prevent external dust, dirt and impurities from entering the inside of the bearing 331, keeping the inside of the bearing 331 clean.

[0036] In some embodiments, see Figures 2 to 4 The magnetic unit 320 includes a magnetic pole ring 321 and a magnetic sheet 322. The magnetic pole ring 321 is embedded in the annular groove 211, and is connected to the bottom of the annular groove 211. The magnetic sheet 322 is connected to the end of the bearing 331 away from the wire ring body 310. The magnetic poles of the magnetic pole ring 321 and the magnetic sheet 322 are opposite, forming a repulsive magnetic force for keeping the bearing rolling unit 330 away. The repulsive magnetic force makes the bearing rolling unit 330 suspended in the annular groove 211, thereby avoiding direct contact between the bearing 331 and the annular groove 211, and further reducing friction resistance.

[0037] In the suspended state, the contact wear between the bearing 331 and the annular groove body 211 is almost zero, which significantly extends the service life of the bearing 331 and the annular groove body 211. The maintenance and replacement frequency required for the components are shortened, thereby extending the overall service life of the equipment.

[0038] In some embodiments, see Figure 2 and Figure 4 The wire ring body 310 includes a T-shaped portion 311 and a hook portion 312 for pulling the wire. The two opposite ends of the T-shaped portion 311 are respectively connected to two bearings 331, and the third end is integrally connected to the hook portion 312. The T-shaped structure provides three-point support for the wire ring body 310, increasing the stability of the overall structure. The connection between the two ends and the bearings 331 ensures the balance and stability of the wire ring during operation, reducing shaking and wear caused by unbalanced loads.

[0039] The arrangement of the T-shaped portion 311 can evenly distribute the force on the wire ring body 310 on the two bearings 331, reducing the load concentration on a single bearing 331. The uniform force distribution can extend the service life of the bearing 331, while reducing component deformation or damage caused by excessive local force.

[0040] In a specific implementation process, the two steel rings 210 are spaced apart, and the width of the space between the two steel rings 210 is smaller than the size of the third end of the T-shaped portion 311. The T-shaped portion 311 forms a physical restriction between the steel rings 210, which can prevent the T-shaped portion 311 from falling off between the steel rings 210. When the wire ring body 310 is running at a high speed and vibrating violently, the T-shaped portion 311 is always kept in the sliding space of the steel ring 210, thereby improving the safety and reliability of operation.

[0041] In some embodiments, see Figure 2 The outer side of the steel collar 210 is threadedly connected to the inner side of the annular base 100 , and the threaded connection provides a reliable fixing method to ensure that the steel collar 210 is firmly positioned in the annular base 100 and is not easy to loosen or shift.

[0042] The threaded connection allows the vertical position of the steel collar 210 to be adjusted by rotation, and the height and position of the steel collar 210 can be precisely controlled, thereby adjusting the interval between the two steel collars 210 so that they remain compatible with the third end of the T-shaped portion 311.

[0043] In addition, both steel collars 210 are threadedly connected to the annular base 100. The precise fit of the threaded connection ensures the concentricity between the steel collars 210 and the annular base 100, improves the stability and consistency of yarn movement during the spinning process, and reduces the problem of uneven yarn tension or thread breakage caused by eccentricity.

[0044] As an alternative embodiment, the outer side of the steel collar 210 and the inner side of the annular base 100 can be connected by snap fastening or directly nested.

[0045] In some embodiments, see Figure 1 and Figure 2 The outer side of the annular base 100 is provided with a flange 110, which can be snapped onto the lifting reinforcing bar of the spinning frame. The snapping of the flange 110 provides a simple and effective fixing method to ensure that the annular base 100 is firmly installed on the lifting reinforcing bar of the spinning frame. The installation and adjustment time of the steel collar-wire ring structure is shortened, which improves the convenience and efficiency of installation, and ensures the stability of the annular base 100 during operation. The flange 110 design also ensures that the annular base 100 is precisely matched with the lifting reinforcing bar when fixed, avoiding installation errors and improving the accuracy and consistency of equipment operation.

[0046] Workflow: First, install the magnetic pole ring 321 inside the two steel rings 210. Then, screw the steel ring 210 located at the bottom onto the annular base 100, and then insert the bearing rolling unit 330 into the annular groove 211 of the steel ring 210. Next, screw the steel ring 210 located at the top onto the annular base 100, and control the distance between the two steel rings 210 so that the bearing rolling unit 330 remains suspended. When the steel ring body 310 drives the bearing rolling unit 330 to roll relatively in the annular groove 211, the bearing 331 and the side wall of the annular groove 211 roll relatively, generating rolling line friction, with low friction force, low friction resistance, and low wear. The bearing rolling unit 330 is suspended relative to the bottom of the annular groove 211, avoiding contact between the bearing rolling unit 330 and the bottom of the steel ring 210, preventing the generation of sliding friction, thereby improving the service life of the steel ring-wire ring assembly and reducing problems such as yarn hairiness and yarn breakage during the spinning process.

[0047] The above description is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be covered by the present invention.
